You may need to access some files, such as a SSH key, from your application hosted on Scalingo. Committing these files on your Git repository is not a good security practice. This page guide you through the steps to securely share that kind of secret files with your application.
Access Secret File From the Application
Let’s say you want the file
private.pem to be available in your application.
You first need to set it in base64 as environment variable of your application:
scalingo --app my-app env-set SECRET_FILE=$(base64 -w 0 ./private.pem)
Then you need to modify the way your application starts so that it first write
the content of the environment variable
SECRET_FILE to the disk then
effectively start the application.
Update (or add) a

And create the script
bin/start-app.sh with the following content:
#!/bin/bash echo $SECRET_FILE | base64 -d > ./private.pem # Start default script for PHP apps $HOME/bin/run
Commit both files and deploy your application. Your application has now access
to your secret file in
